To provide an external communication device for an elevator that is able to respond to a call from inside a car, from a car stop without installing a dedicated telephone device at the car stop.SOLUTION: An external communication device for an elevator includes: an emergency call device provided in an elevator car; and a relay device provided on a car-stop operation panel of the elevator. When a call button of the emergency call is pressed from inside the car, a control device of the relay device performs a ringing process for emitting a ringing sound from a ringing device. When one of an unspecified number of people who heard the ringing sounds makes a communication connection request from the own external terminal, the control device receives the communication connection request and performs a communication connection process for establishing a mutual wireless communication with the external terminal. Thus, voice communication between the emergency call device and the external terminal can be made possible.SELECTED DRAWING: Figure 3

    【課題】専用の通話機器を乗場に設置することなく、かご内からの呼出しに対して乗場から応答することのできるエレベーターの外部連絡装置を提供する。【解決手段】エレベーターの外部連絡装置は、エレベーターのかごの中に設けられた非常通話装置と、エレベーターの乗場操作盤に設けられた中継装置と、を備える。かごの中から非常通話の呼出し釦が押下された場合、中継装置の制御装置は、鳴動装置から鳴動音を発する鳴動処理を行う。鳴動音を聞きつけた不特定多数のうちの一人が自身の外部端末から通信接続要求を出すと、制御装置は、通信接続要求を受けて、当該外部端末との間で相互無線通信を確立する通信接続処理を行う。これにより、非常通話装置と外部端末との間の音声通話が可能となる。【選択図】図3
